# Re: Tegmark's New Book

```Brent,

The "elements of the set" are the information encoding the current state of
the universe and how it is evolving - whatever that may be. What that may
be needs to be further clarified. I've put forth a whole list of likely
possibilities on this group over the past week or so including several
today which I'm not going to repeat here.```

The equations you present are not nearer or farther, they don't even exist
in computational reality. What exists is actual code computing actual data,
not abstract static equations absent actual real data. What is
computationally 'nearer' is data that will interact to compute actual
interactions of say elemental particles. Computational nearness produces
dimensional nearness as dimensionality emerges from the computations.
That's how we know what is computationally nearer. There is no topology of
this non-dimensional computational space. It's all logical connections and
associations, nearness is what interacts computationally.

And as a bonus, GR emerges automatically if we take mass-energy as the
relative scale of the dimensionality that emerges. That automatically
dilates spacetime around mass-energy. Visualize this as a GR rubber sheet
model in which the depression around a mass is caused by a dilation of the
grid cells of the surrounding rubber sheet and you'll see how this works.
